The purpose of this study was to investigate the characteristics of the golf swing motion associated with the club head acceleration in driver shot. The subjects were 8 female professional golfers and they performed 10 shots with own driver in a laboratory. During the performing the driver shot, 3D coordinates of body and club landmarks were obtained using the motion capture system with operating at 250 fps. We found that the energy in the club head was mainly consisted of the transitional kinetic energy, and the effect of the rotational kinetic energy and potential energy were small. The maximal value of the changing rate of head speed and left wrist speed was significantly greater in professional group (p<0.01). In professional group, the speed of wrist, elbow, and shoulder decreased rapidly after achieving a peak. It was suggested that the head speed could be accelerated by decelerating joint speed in impact.
